Backup Battery

The CR-2032 coin-cell backup battery protects your data when the main battery runs out of power. The backup battery does not provide enough power to operate your hp Jornada, but it will preserve your data for up to 1 day after the low main battery warning is displayed.

The backup battery is not recharged while your hp Jornada is connected to ac power. When you see a warning message indicating that the backup battery is low, you should replace the backup battery as soon as possible.
